Be it lrnoivn that l, THOMAS lV. llliLLriiMs, a subject of the'King of Great l-ritain, and a resident of Pittsburgh, Allegheny County, Pennsylvania, have invented certain new and useful improvements in Car lfilheels, ot which the following is a specification.

This invention relates to car Wheels and more particularly to Wheels ot this type designed for use in mines, and has for its object the provision of a Wrought or Llorged steel Wheel. li aving a self-lubricating hub.

A further object is the provision ot a Wheel of this type having novel means tor forming a lubricant retaining receptacle in the hub portion thereof.

A still further object is the provision of a Wheel of this type having the novel design, construction, and combination of parts described in the following` specification and illustrated in the accompanying` drawings, in Which- Figure l is a side elevation olI a wheel constructed in accordance ivith this invention.

Figure 2 is a sectional elevation on the line lll- Il of Figure l.

Referring more particularly to the dran'- ings, the letter A designates the Wrought metal or forged portion oit the Wheel as a Whole, Which comprises the usual flanged tread or rim portion 2, a comparatively thin plate or web portion 3, and a relatively heavy hub portion a. f

rlhe hub portion 4 is counterbored from one end nearly to the opposite end, the closed end is then bored to form an apen ture 5 of appreciably less diameter than the counterbore, and the opposite end of the counterbored portion is again counterbored for a short distance to form an enlarged portion 6 and a shoulder 7.

A bushing 8 of cast iron or other metal is fitted Within the counterbored hub and is of such diameter that it will tit snugly Within Specification of Letters Patent.

Patented July i8, i922.

1922. serial No. 560,420.

provided With an annular flange 9 adapted to fit snugly ivithin the enlarged portion G oft the counterbore and to abut the shoulder 7, thus cooperating with the closed end ot the counterbore to form a closed lubricant receiving and retaining cliamber or receptacle l0.

A suitable lubricant inlet or oil hole ll is termed in the hub and is closed by a screiv plug l2.

The bushing 8 is shown provided with a series of apertures la through its side Wall to permit the passage of the lubricant from the chamber or receptacle 10 to the axle of the vehicle upon which the wheel is mounted, although it will be understood that one aperture may be used if desired.

Wheels ot this construction Will have a much longer lite than the old style of cast `vheels used on mine ca as, will. be compara tively cheap to nuinu'tacture, will bc selilubricatiug, and will produce a minimum oilE ij'riction on the axles due to the unlike metal bushing.

l claim:

lfn a 'forged steel car Wheel. a hub portion counterbored For the greater portion. oi its length and having a smaller bored aperture in the bottom iva-ll ot said counterbore, said counterbored portion of' said hub having an enlarged annular portion at its open end forming a shoulder, and a bushing oli' a diameter that will lit snugly Within said bored aperture fitted Within said counter` bore and having` one end projecting into said bored aperture, an annular flange on the opposite end ei said bushing adapted to snugly fit Within the enlarged annular portion of said counterbore and abut said shoulder thereby Aforming a closed annular lubricant retaining recess, said bushing being provided with pertorations to permit the passage of lubricant therethrough.

ln testimony whereof l have hereunto set my hand.
